3 Claims.

The present invention relates to improvements in liquid dispensers forgarbage cans and has for an object to provide an improved device of thischaracter in which small quantities of disinfecting and deodorizingliquid can be dispensed.

Another object of the present invention is to provide an improveddispenser wherein a disinfecting and deodorizing liquid is dischargedupon the contents ofa garbage can, trash can or the like by the normaltilting of the cover of the can when removed from and replaced upon thecan.

A further object of the present invention is to provide a device of thiskind which can be attached to garbage cans and the like already inservice or can be built into the cover of the can during themanufacturing thereof.

A still further object of the present invention is to provide animproved construction which is simple in operation, has no moving partsto wear out and requires practically no attention except refilling withthe disinfecting and deodorizing fluid.

The present invention aims to provide an improved dispenser in whichvapors from the volatile disinfecting and deodorizing fluid will at alltimes be conveyed to the garbage regardless of whether or not the coveris removed.

With the foregoing and other objects in view, the invention will behereinafter more fully described and more particularly pointed out inthe appended claims.

In the drawings, in which the same parts are denoted by the samereference numerals throughout the several views,

Figure 1 is. a top plan view of the improved device constructed inaccordance with the present invention and showing a portion of a garbagecan to which it is attached, a

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1,

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 2,

Figure 4 is a view similar to Figure 1 showin a modified form of theinvention,

Figure 5 is a vertical sectional view on the line 55 of Figure 4, and

Figure 6 is a horizontal sectional view on the line 66 of Figure 5.

Referring more particularly to the drawings, I0 indicates a cover for agarbage can or the'like II with which the improved device is associated.The improved liquid dispenser is in the form pf a substantially circularcontainer having a downwardly and inwardly tapering side wall I2 and aflat bottom l3. A dish shaped or inverted cone 2. shaped bafile I4 isdisposed within the container and secured by welding or the like to theinner face of the side wall I2. The bafile I4 has a plurality ofcircumferentially arranged apertures I5 which are disposed adjacent itsperiphery and a centrally located opening l6. Four holes I! are formedin the baflle I4 around the opening I6 in angularly spaced apartrelation.

A tube I8 is secured to the under surface of the baffle M by Welding orthe like in communication with the opening I6 of the baffle. The tube I8extends downwardly below the bottom l3 through a suitable openingtherein. A top I9 is secured to the upper edge of the side wall 12 bywelding or the like and has a pair of diametrically opposed aperturedlugs 20 so that the top can be detachably mounted on the cover III ofthe garbage can by bolts and nuts 2|.

The bottom of the baffle I4 is spaced from the top I9 to form an airspace 22 therebetween and is also spaced from the bottom l3 of thedispenser to provide a chamber 23. A screw threaded nipple 24 is mountedin a suitable opening in the side wall I2 and forms a filler openingwhich communicates with the chamber 23 for the introduction thereinto ofdisinfecting and deodorizing liquid 25. A threaded cap 26 is removablyattached to the nipple 24 to close the filler opening.

In the operation of the dispenser the cap 26 is removed from the fillernipple 24 and disinfecting and deodorizing liquid is introduced into thechamber 23 until it is about half filled as indicated in Figure 2. Thecap 26 is then replaced and the dispenser is ready for use.

When the cover I!) of the garbage can II is removed for placing garbagein the can, the normal tiltingof the cover will move the dispenserthrough approximately degrees from the position shown in Figure 2. Thismovement of the dispenser will cause the disinfecting and deodorizingliquid 25 to flow through some of q the apertures I5 and holes I! uponthe upper surface of the baffle I4. The apertures l5 and the holes I!are of small diameter so that only small quantities of the liquid 25will flow through the apertures I5 and holes I! with each tiltingoperation of the dispenser. When the cover of the garbage can isreplaced that portion of the liquid 25 which has accumulated on theupper surface of the baffle M will gravitate to the opening l6 and holesI! of the baiile. Some of this accumulated liquid will return to thechamber 23 by means of the holes I1 and the remainder of it will flowdownwardly through the tube l8 upon the garbage in the can II.

This arrangement will assure that only minute quantities of the liquidwill be deposited upon the garbage with each removal of the cover. Thesupplying of the liquid in minute quantities is suflicient to disinfectand deodorize the garbage since each time the cover is removed to placeadditional garbage, a charge of the fluid is deposited on the additionalgarbage. Accordingly there is no waste of the liquid and yet all of thegarbage is efliciently treated to effect complete disinfecting anddeodorizing of all the garbage in the can.

The provision of the air space 22 allows the accumulated liquid on thebaffle to flow out of the dispenser upon the garbage. This space is thenvented by the discharge tube to allow necessary air space for the nextoperation.

No dispensing of the liquid is possible without the removal of the coverand tilting motion. resulting therefrom. Deodorizing of the contents ofthe garbage can is, however, always taking place due to the evaporationof the volatile disinfectant which is constantly being conveyed to thecontents of the garbage can by the apertures l5, the holes l1 and theopening 16 of the bafiie M to the tube I8. If desired, the garbage cancover can be removed andreplaced without dispensing the liquid by nottilting the cover.

Referring to the modification shown in Figures 4; 5 and 6, 21 indicatesa cover for a garbage can or the like having a handle 28. The cover 21has its central portion depressed to form a downwardly and inwardlytapering circular side wall 29' and a circular bottom 30 to provide asubstantially circular liquid dispenser. A baffle 3| has a peripheralflange 32 which is secured to the cover 21 by welding or the like andhas a series of circumferentially disposed. openings 33 arrangedadjacent its peripheral flange 32. The bafile 3| is substantially dishshaped or inverted cone shaped and has a centrally disposed opening 34which is surrounded by four holes 35 arranged in angularly spaced apartrelation. A tube 36' is secured to the under face of the baffle 3| andthe bottom 30 by welding or the like in communication with the centrallydisposed opening 34 of the bailie. The lower end of the tube 36- extendsthrough and below the bottom 30 of the liquid dispenser. A top 31 issecured to the flange 32 of the baffle 3| in any suitable manner, suchas by welding.

.The bottom of the bafiie 3| is spaced from the top 31 to form an airspace 38 therebetween and is also spaced from the bottom 30 of thedispenser to provide a chamber 39.

A screw threaded nipple 40 is mounted in suitably aligned openings' inthe bafile 31 and the top 31 and forms a filler opening whichcommunicates with the chamber 39 for the introduction thereinto ofdisinfecting and deodorizing liquid 41. A threaded cap 42 is removablyattached to the nipple to close the filler open- It will be noted inthis modification of the invention that the sidewall and the bottom ofthe dispenser are formed integrally with the cover of the garbage canand that in this form of the invention the dispenser isbuilt into thegarbage can at the time of manufacture thereof.

The operation of the modification of the in vention shown in Figures 4,5 and 6 is substantlally the same as that described in connection withthe form of the invention shown in Figures 1, 2 and 3.

In both forms of the invention the tubes [8 and 36 can be made of copperand the other parts of sheet metal. The capacity of the dispenser isabout twelve ounces but preferably only six ounces of liquid are placedin the dispenser. This supply is sufficient under ordinary conditions ofuse for a period of from three to four months. One dispensing of liquidis approximately .0124 of a U. S. fluid ounce. The amount of liquidwhich is dispensed at each operation can be varied by changing the sizesof the apertures and holes in the bailie.

It will be noted that the present invention eliminates the use of wicksand sponges which would get clogged with dust and dirt and there are nomoving parts, such as valves to get stuck or wear out.

The present invention is also adaptable to the following uses:

1. The device may be attached to toilet or commode seats for dispensinga disinfectant or deodorant. The liquid would be dispensed in the bowlby tilting or hinging motion of the seat. The vent pipe would allowvaporized deodorants to be emitted at all times.

2. The device may be attached to a mop, etc., for dispensing floorpolish, floor oil, liquid floor \v'ax, etc. The motion of the mop wouldcause regular amounts of fluid to be dispensed regularly.

3. Pivots may be installed on the device and the same attached to walls,etc., of wash rooms for dispensing liquid soap.

4. This device may be altered in size as required for dispensing exactamounts of any type of liquids by tilting motion, normal or mechanical.The device may be adapted for dispensing cream. or milk in exactamounts; for dispensing liquid soda fountain extracts syrup, etc.; fordispensing any type of liquid in given. amounts by bafiie and tiltingmotion.

It is obvious that various changes and modifications may be made in thedetails of construction and design of the above specifically describedembodiment of this invention without departing from the spirit thereof,such changes and modifications being restricted only by the scope of thefollowing claims.

What I claim is:

1.
